o.k., I do not know about oracle, but it seems that an attempt
has been made to write a null into a non-nullable column.
For example, that can be the case if you have several classes mapped to
the same table and you insert an instance that does not have
any field mapped to that column.
Please find out (by using P6Spy) what the offending SQL
statement is. Then find out what the values of the
fields of the object being written are.
Then we can see if this is a bug.
Possible workaround: make that column nullable or specify a
database default.
Olli
